In this tutorial, we’re going to explore the motivation behind Java preview features, their difference compared to experimental features, and how to enable them with different tools.
As it’s probably clear to everyone by now, Java feature releases are delivered every six months. This means less waiting time for new Java features, but at the same time, it means also less time to react to feedback about new features. This is Java we’re talking about here. It’s used to develop a huge number of production systems. As a result, even...
Java preview features are completely specified and developed features that are going through evaluation. Therefore, they have just not reached the final state yet. Because of their high quality, different JDK implementations must include all preview features planned within each Java delivery. However, a Java release still can’t support preview feat...
Preview features are disabled by default. To enable them, we must use the enable-previewargument, which enables all preview features at once. The Java compiler, as well as the JVM, must be of the same Java versionthat includes the preview feature we want to use. Let’s try to compile and run a piece of code that uses text blocks, a preview feature w...
In this article, we’ve introduced preview features in Java, why we have them, and how they differ from experimental features. Then, using the text blocks preview feature in JDK 13, we explained step by step how to use preview features from Eclipse, IntelliJ, Maven, and the command line.
There are several categories of new, nonfinal features: Preview, for new Java platform features fully specified and implemented but yet subject to adjustments. Experimental, mainly for new features in the HotSpot JVM. Incubating (also known as incubator modules), for potentially new APIs and JDK tools.
Mar 19, 2024 · Enables efficient sharing of immutable data within and across threads. Value: Ease of use — Provides a programming model to share data both within a thread and with child threads, to simplify reasoning about data flow. Comprehensibility — Makes the lifetime of shared data visible from the syntactic structure of code.
